What is the difference in engine yearshttps://www.mazdas247.com/forum/showthread.php?123867488-What-is-the-difference-in-engine-years&goto=newpost
Thu, 21 Feb 2019 02:18:43 GMTHey everyone, Iíve had a 2013 cx9 touring for about 2 years and just had a water pump failure. Iím trying to find engines with decent mileage but I keep seeing differing opinions as to what engines will just drop in. It looks like on 2013&2014 engines will be just a drop in for mine. What changed in 2015? There are better options currently if I can use a 2015 engine.

Mon, 11 Feb 2019 01:49:13 GMTHey guys,

So we bought our CX-9 about 4 months ago. It's been great so far apart from the transfer case having almost zero oil in it (glad i checked and re-filled before failure). Anyways, on our way back from a 400km trip, half an hour from home, the car lost power. I had the cruise control on and it kept trying to shift into a lower gear to get the car back up to speed. Anyways, i took it off cruise and could not accelerate, the more i tried the more it just slowed down. A few seconds later the engine light came on and started flashing. I then knew i had a misfire in one or more cylinders. We limped it home and i hooked up my scan tool and got the following codes:

P0301, P0351, P0352, P0354. After some quick research, i found the tsb from mazda about the ECM and ignition coils. I finally got the time to take it all apart today, and found ignition coil #1 melted. the rest seem to be fine. Now, since they've never been done, i plan to get 6 new plugs and coils. BUT, i do not know how to test the ECM to see if it will just melt the ignition coil again. Is there a way to test to see if the ECM is good/bad?

Now, the only issue i have is, if i do go ahead and order a new ECM (i found a seller on ebay who will pre-program it with your vin number), do i still have to go to the dealer to get the keys programmed or is that something i can do myself, and if so, how?

I live in Canada, so shipping out my ECM for repair would take quite a while i assume, but i don't want to have to rip it all apart and spend the money on new coils again. Also, my cx9 is originally a USA car (if it matters). It has 118,000 miles. Lastly, its the switchblade key.

Anyone hear this on their vehicles? The weather has been really cold here (regularly in the single digits or negatives) but I've never had an engine make knocking noises like this when shutting it off in these temperatures, or at all, before. This was after a 25-30 minute commute and the heat was blowing warm so the engine definitely got up to normal operating temps. If this is normal, fine, but it's weird and I have a hard time believing it should be.

I've always run my CX-9 on premium gas, maybe a few tanks on regular, but that shouldn't matter since the engine takes either. I otherwise don't rev the crap out of the engine, especially not in this cold weather and I don't push the vehicle if the engine hasn't warmed up.

Any theories on this noise? I otherwise plan to call the dealership if the issue persists.

Tue, 05 Feb 2019 21:11:28 GMTI know pretty much every year can have PTU trouble but i am wondering if it is only the 2007 that also have the problem of transmission splines shearing when the PTU goes south.

Also, for the water pump trouble, was that only on the 3,7L? didn't recall anyone with the 3.5 (in 2007) having this issue. Was that issue from 2008 to 2013 only?

If you exeperienced either the water pump or the transmission spline trouble, what year was your cx-9?

i personnaly had trouble with the transmission splines but not the water pump on my 2007

Tue, 05 Feb 2019 01:42:00 GMTHey all, looking for an opinion on a couple of things. I have a 2017 CX-9 with 20,000km (~12,000 miles) in Canada.

1. The photo attached is the dipstick after an oil change. This was the day after the oil change and the car was sitting on flat ground. I've spoken to the service manager several times, and he states the oil capacity is 5.9 litres (vs 4.8 in the manual) and that this amount "should be fine". Any thoughts on if this amount is too much?IMG_0509.jpeg

2. I'll hold my hand up here and say I am partially responsible, but I trust that the dealer is being level with me and when the wrench comes on for the oil change etc I make an appointment and bring it in. On the latest oil change, when I put the paperwork in my binder (I'm that guy) I noticed the last oil change was 4 months previous. Before that is was 5, then 6 and then 6 (and then new). I asked the service manager and he told me they are changing it to 4months to promote longevity in the engine. The manual states 6 months and 12,000 km (7,500 miles) in Canada (I am in Vancouver area) and much longer in the US. The question is, does this dealer have a legit reason, or is this clearly the case of the dealer playing a shyster move?

Overall I quite like(d) the dealer here - but these two things are driving me a little crazy. They did stand up and replace the nav screen that they scratched during a service with is a plus, but hard to still trust them with the other behaviour?

It is also worth noting that they offered me several free oil changes to make up for this, but if they are overfilling it and doing this other stuff - is free really worth it?

Wed, 23 Jan 2019 16:46:36 GMTIím far from an expert, but doesnít 40k miles seem very early for spark plug replacement in a 2016+ model? Thatís what the service manual calls for. Seems crazy to me. The dealer just quoted me $250 for parts and labor. That also seems crazy.Iím far from an expert, but doesnít 40k miles seem very early for spark plug replacement in a 2016+ model?
